I have had M-1's for about three years, about 9 months ago getting the new PX panels. Initially, I was powering them with a hybrid tube amp made by the Moscode people with good results (this proprietary design was built on the old 600 with two power supplies and a bunch of other goodies on two chassis). The only problem was that there was not quite enough punch to the sound (I listen almost exclusively to classical music). I then changed to the Bryston 14B SST with excellent results. I had the amp upgraded to the Swedish choke and things got even better. For some reason, SL owners avoid this amp (maybe because they think it is too cheap).
Amp advice for Sound Lab M-2's
Looking for opinions for a amp to use with my Sound Lab M-2 speakers. I am down to considering the Bryston 7b – SST, Parasound JC – 1, and the new Sanders Sound ESL amp. The former owner of the M-2’s used a Pass X-350, but I found that it sounded dry, and very thin. No warmth at all. Lots of older Krells out there, great bottom ends, but again often very cool sounding. I’m not that familiar with the Levinson’s, another option, maybe. The Sound Labs do need a good honest 300 watts > 8 ohms, and 600 watts > 4 ohms. Most amps don’t have the combination of voltage and current ratings to handle the speakers. I am leaning towards the Brystons. Overall they seem to be an amp that is easy to live with, while maybe not the best over all, they do a lot right. Ideas and experiences appreciated. By the way, the listening room is 23x21, with a ceiling that is 9 feet on one long wall, and slopes up to 16 feet on the other long wall. 15 feet of the highest long wall is open right in the middle of the wall. So the room can really suck up speaker output. Thanks.
